N2 - In the next generation Wireless Local Area Network (WLAN), IEEE 802.11 regards improving the throughput of the network as a major technical goal. Distributed Multiple Input Multiple Output (D-MIMO) System is an important issue to improve system capacity efficiency, but D-MIMO technology requires extremely high clock consistency between nodes. Therefore, this paper proposes a synchronization protocol based on Orthogonal Frequency Division Multiple Access (OFDMA) for D-MIMO. Firstly, this paper chooses a new clock synchronization process for the synchronization protocol (Two-Way Message Exchange), which is characterized by high synchronization accuracy. Second, we propose and refine the procedure of the synchronization protocol and design the frame structure of the protocol to make it compatible with IEEE 802.11 frame format. The simulation results show that with the increase of the number of APs in D-MIMO, proposed synchronization protocol reduces the overhead by nearly 50% compared with single user (SU) based synchronization protocol. Moreover, the clock synchronization accuracy increases with the increase of the number of information interactions.
